Sean, your seeming inability to even hint at the possibility that you might be wrong makes it impossible to discuss this in a logical manner. I'm leaving the topic after this.
First you claimed that the stylus was "slicing" through the vinyl like a diamond cutter through glass. When I point out you are wrong because it is "riding along the surface" you change to "scraping," which is in effect exactly the same thing I just said, and make a condescending remark like I don't get it. You should go into politics.
The heat isn't generated simply because the stylus isn't centered. It comes from the stylus tracking the modulations. Heavily modulated grooves produce more heat than lightly modulated ones no matter how well centered the stylus is. Centering has nothing to do with it.
This is a well proven fact, not an opinion. You are wrong. No matter how many times you put forth the centering argument, you will still be wrong.
Also, there isn't a manufacturer in the world that uses a servo motor controller to compensate for instantaneous stylus drag. Why? It won't work. No matter how fast, servos will always be reacting to something that happened in the past. Again, not an opinion. It is a fact that you are unwilling to acknowledge.
All servo controlled linear arms to date have been inferior to other designs for the same reasons. This is also a fact. I do believe given the advances in servo motors since the attempts in the early 80's, and the speed of todays microprocessors, that it should be possible to build one that will work well. Perhaps combining the tracking capabilities of the newer laser tonearms as the feedback to the controller along with high speed processors might work. The laser tracker could be positioned ahead of the stylus, in effect predicting where it needs to be instead of reacting to it being where it shouldn't be. Feel free to use and develop that idea.
